Abstract

The present invention provides a substrate with antireflection films, which has excellent antireflection properties to incident light at an oblique angle from the film face side and high transmittance. Moreover, the antireflection films of the present invention provide a reflection color tone that does not tend to be bluish. This object is achieved where the substrate with antireflection films comprises a transparent substrate and at least two antireflection film layers deposited on one side of the transparent substrate as described herein.
